Graphing polynomials using zeros
WebGraphs of Polynomials Using Zeros x- and y-intercepts, signs, and leading term tests used to sketch a graph. Add to Library Share with Classes Add to FlexBook® Textbook … WebThe zeros of a polynomial are the solutions to the equation p(x) = 0, where p(x) represents the polynomial. If we graph this polynomial as y = p(x), then you can see that these are the values of x where y = 0. In other words, they are the x-intercepts of the graph.

WebExample 2: Determine the end behavior of the polynomial Qx x x x ( )=64 264−+−3. Solution: Since Q has even degree and positive leading coefficient, it has the following end behavior: y →∞. as . x →∞ and y →∞ as x →−∞ Using Zeros to Graph Polynomials: Definition: If is a polynomial and c is a number such that , then we say that c is a zero of P. WebOct 31, 2024 · How to: Given a graph of a polynomial function, identify the zeros and their mulitplicities If the graph crosses the x -axis at a zero, it is a zero with odd multiplicity. If the graph touches and bounces off of the x -axis, it is a zero with even multiplicity. The higher the multiplicity of the zero, the flatter the graph gets at the zero.
